LOOM.

SPECIFICATION forming part of Letters Patent No. 641,763, dated January 23, 1900.

Application filed August 1'7, 1899. Serial No. 727,472. (No model.)

To all whom it may concern.-

Be it known that I, ALVAH W. CLEMENT, of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvementin Looms, of which thefollowing description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention relates more particnlarlylo looms provided with automatic filling-suplying mechanism controlled by or through a feeler which at intervals feels the filling in the shuttle and which when the filling has been exhausted to a predetermined extent causes the supplying mechanism to operate to effect the introduction of a fresh supply of filling, a loom of this type forming the subjectmatter of United States Patent No. 626,187, dated May 30, 1899.

As the fresh filling is transferred the partially-spent filling-supply is ejected from the shuttle, carrying with it the end of filling leading from the edge of the cloth; and my present invention has for its object the production of' means to part or sever this filling end, so that not only will the length of thread pulled away by the ejected filling-carrier be as short as possible, but the parting means will carry the length of filling between it and the edge of the cloth into position to be parted or severed by a thread-cutting temple closely adjacent the edge of the cloth.

I have herein shown one practical embodiment of my invention as applied to a loom of the character shown in Patent No. 626,187, referred to, and to operate in conjunction with a thread-cutting temple, such as shown in United States Patent No. 585,465, dated June 29, 1897; but my invention is not restricted in its application to such construction of loom nor to the thread-cutting temple herein shown.

Various novel featu res of my invention will be hereinafter described in the specification and particularly pointed out in the claims.

Figure 1 is a front elevation of a suflicient portion of a loom to be understood, taken at the side provided with filling-supplying mechanism and having one embodiment of my invention applied thereto. Fig. 2 is a right hand side elevation of the apparatus shown parting means in normal position. Fig. 3 is 'an enlarged top or plan View of a portion of the loom, showing the parting means in operative position and just before the end of filling between said means and the edge of the cloth is brought into position to be engaged by the thread-cuttin g temple,also shown. Fig. 4 is aperspective view, enlarged, of the breastbeam at the left-hand side of the loom, showing the feeler and a portion of the connecting devices between it and the thread-parting means. Fig. 5 is an enlarged innerside elevation of the parting means in normal posi tion. Fig. 6 is a similar view showing the parting means in position to grasp and to sever the filling when the transferrer is operated to effect a change of filling. Fig. 6 is a detached view of one of the jaws of the filling-holder shown in Figs. 5 and 6. Fig. 6

is a perspective view of the cooperating jawthereof. Fig. 7 is an inner side elevation of the filling-parter per se; and Fig. 8 is a detached view of the segmental lifter which operates to open the parting and holding members, said arm being shown in dotted lines, Fig. 1.

In carrying out my invention I have so constructed and arranged the fillingparting means that they will only operate whenthe shuttle is properly'boxed, said means acting as a shuttle-feelerto detect the improper boxing of the shuttle.

Referring now to Figs. 1 and 2, the loomframe A, breast-beam A, the lay A having the bottom of one of its shuttle-boxes cut away below the self-threading shuttle S to permit the passage therethrough of an ejected filling-carrier, the filling-supplying mechanism, comprising connected rotatable plates suitably shaped to hold the filling-carriersb, the stud f, transferrer f, mounted thereon and having the depending end f and a finger patent,the en df of the transferrer has mounted upon it a headed rocker-stud m, controlled by a spring 3, said stud having an arm m provided with a lateral lug m, said arm having an attached notched dog m to be engaged by a hunter 0 on the lay when a change of filling is to be effected.

The loom-frame is provided with a bracket A on which is pivoted at 10 a yoke Y, one of its upturned arms 3 directly engaging the lug m, a lateral stud or projection on its other arm, and preferably provided with an antifriction-roll 7, being normally engaged by a detent-finger d fast on the rock-shaft d and normally maintained in the position shown by a strong spring S attached at its ends to said finger and to the loom-frame, respectively. In said Patent No. [528,228 the other arm of the yoke Y is upturn ed and bent rearwardly to form a shuttle-feeler, and in my present invention said arm y is upturned and bent rearwardly; but it is bifurcated to form two branches P and h (see Fig. 3,) the former supporting the parting devices and the latter having mounted upon it the holding means for the filling end. The rearwardlyextended end of the branch 19* is notched at 19, Fig. 7, and a steel blade p is fixed to the inner face of the branch, with its sharpened edge above the notch, while a movable blade 13 is mounted to rock on a pin or stud 25, extended from one to the other branch, said blade being held from free movement by a suitable friction-washer 26, Fig. 3. At its front end the movable blade has a cam-slot 1), adapted to be entered by the reduced end 11 of a laterally-extended lug p attached to an actuating-arm p herein shown as mounted on the end of the stud 25, projecting beyond the branch 72. and frictionally held by a washer 27, the lateral lug p traveling in a slot 28 in the branch h (See Fig. (3.)

Referring to Fig. 5, wherein the actuatingarmp is shown in normal position and against a stop 29, the lug p will have moved downward past the fulcrum 25 of the arm 29 far enough to engage the bottom of the slot 19 and rock or tip the blade p thereby wiping its cutting edge over the edge of the fixed blade 1.12, the parting device being thus maintained normally closed.

The branch h is cut away at its extremity to leave an overhanging projection h, on which is mounted a weighted jaw 7L2, fulcrumed at 30 and having a slot 31 near its front end to receive a guide-stud 32, the enlarged base 7&3 of thejaw being shown in Fig. 6 as longitudinally concaved to form a seat for a facing h of rubber or other suitable yielding material, the weight of the jaw 71 being sufficient to turn it into the position shown in Fig. (5 when free to move, the holding device, com prising the jaws 72, and h then being open. The cooperatingjaw h is shown detached in Fig. 6, it having an upturned hooked front end h to receive a pivot h by by which it is fulcrumed on the branch h the hooked end being notched on its upper edge, as at it to receive the pin or stud 25 when the jaws are closed, the front upright edge of the jaw being straight from 3 to 4 and then curved to form a notch or recess 71 When the actuating-arm p is in normal position, Fig. 5, the lateral lug 19 rests against the front edge of the jaw h below the upper corner 4 thereof, positively maintaining the latter in engagement with the concaved portion h3 of the gravity-jaw 72. as it maybe termed, the front end of the latter being lifted relative to its fulcrum 30. When, however, the actuating-arm p islifted into dotted-line position, Fig. 5, as will be described, the lug 71 operates to first open the blades of the parting device and then as the lug travels up along the edge 3 4 of the jaw h to open said jaw as the lug arrives at the upper corner 4, the notch h affording a clearance for the lug at such time. As the jaw h is thus rocked into open position the gravity-jaw 7L2 moves into the relative position shown in Fig. 6, and the parting and holding devices are ready to operate upon the filling-thread when the latter has been exhausted to a predetermined extent.

Referring now to Fig. 4, the filling-feeler e is shown as forming part of an arm a", pivotally mounted at a. on the feeler-carrier a", as in United States Patent No. 626,187, the feeler entering the shuttle through an opening therein and through a slot in the front wall of the shuttle-box, and, as described in said patent, the feeler contacts with the filling when the lay beats up, so that when the filling is exhausted to a predetermined extenta stud a will contact with the shuttle-body before the feeler engages the filling. The arm a will then be swung inward, viewing Fig. 4, and a dagger ct on said arm will engage a spring-controlled blade a and rock its supporting-stud (7. as the lay completes its forward movement, such rocking of the stud moving a link 0 in the direction of thearrow 50, Fig. 4, to actuate a setting-cam c, which in turn acts on a dog d to rock the arm 01 and bring a latch connected therewith and not shown herein into position to be acted upon by the usual weft-hammer, the arm (Z being fulcrumed at (l on a finger (Z fast on the rock-shaft d, all as in said Patent No. 626,187. When the weft-hammer engages the latch, the arm 61 is operated to rock the shaft (1 through its attached finger d in the direction of the arrow 55, Fig. 2, the detentfinger d will be raised, permitting the spring 8 to turn the dog m into position to be engaged by the hunter 0*, and at the same time the lug on will act upon the arm y to swing the yoke Y upon its fulcrum l0, and if the shuttle is properly boxed the bifurcated end of the arm y will be moved into the position shown in Fig. 6, directly above and adjacent the raceway of the lay, as the latter completes its forward beat.

The stand 9, Fig. 4, is provided with an extension, upon which is fulcrumed at 0 a lever 0 forked or notched at its upper end to embrace a pin on a collar 0 adjustably secured by a set-screw 0 on the link 0 the lower end of said lever having pivotally connected therewith one end of a rod 0 the other end of said rod being pivotally connected with a short depending ear 0, (see Figs. 1 and 8,) fast on a shaft 0 mounted to rock in a part A of the bracket A secured to the loom-frame, said shaft being at right angles to the fulcrum 10 of the yoke Y. At its rear end said shaft 0 has secured thereto by a set-screw 80, Figs. and 6, the hub of a lifter 0 shown as a segmental arm extended beneath the widened end p of the actuatingarm 19 the lifter moving the arm 19 to effect the opening of the thread parting and holding devices.

When the link a is moved longitudinally, as has been described, the lever 0 is rocked to move the rod 0 oppositely to the arrow 50 and the shaft 0 is rocked to raise the lifter 0 into dotted-line position, Fig. 5, to thereby raise the outer end of the actuating-arm into dotted-line position, placing the holding and parting devices in condition to receive the fillingthread, as has been described. This separation of the blades of the parting device and the jaws of the holding device takes place before the shaft cl has been rocked, so that when the latter is operated the yoke swings back and assumes the position shown in Figs. 3 and b as the lay completes its forward stroke, it being supposed that the shuttle is properly boxed, the fillingthread if entering between the jaws 71/2 71 and the blades p 99 The transferrerf has an elongated hubf Fig. 1, which passes through the stand A and an arm f is secured to the projecting end of the hub, said arm having pivotally connected therewith at f a depending leg f reduced at its lower end atf to leave a shoulderf", the end f passing beween the branches p h of the yoke-arm y and between the laterally-extended lug p and a friction-roll p mounted on a stud p extended from one to the other branch, as herein shown. With the parts in the position shown in Fig. 6, when the transferrerf descends to effect a transfer of filling the depression of the legf brings the shoulderf into engagement with the lug p and depresses it until the arm p is stopped by the stop 29, the roll p engaging and guiding the leg until the arm p reaches its normal position relative to the yoke,'and then the space between the lug p and the roll p will have increased suffioiently to permit the sho ulderf to pass by the lug as the transferrer completes its transferring movement. As the lugp is thus depressed it acts to close the jaw it against its fellow h before the part of said lug has engaged the bottom of the slotp of the movable cutting-blade 29 so that the filling is engaged and held by the holding device before it is severed by the blades of the parting device. This prevents the filling from twisting out of the range of the holding device, as it draw through the. jaws after being would be apt to do were it severed before being held, as described. As soon, however, as the filling-thread is firmly held by the holding device the parting device operates to part or sever the thread near the shuttle, as will be evident from an inspection of Fig. 3, so that when the partially-exhausted filling-carrier is ejected from the shuttle by the entrance of the fresh supply of filling the length if of filling carried away by such ejected filling-carrier will be as short as possible, it being usual to provide a box or other convenient receptacle for the ejected filling-carriers. The filling end is now severed and its loose end is held between the jaws of the holding device, and as the filling-transferrer resumes its normal position, rocking the arm f to lift the leg f, the rock-shaft d will be released in the usual manner to permit the spring S to depress the detent-finger d thereby returning the yoke Y to its normal position, (shown in Fig. 5,) it being remembered that the holding device still retains its grasp upon the filling end. As the yoke swings into normal position the filling end is drawn forward and into the path of the cutting device of a th readcutting temple, (shown only in Figs. 2and 3,) the temple herein illustrated forming the subjectmatter of United States Patent No. 585,465, hereinbefore referred to, it being only necessary to herein state that the movable member 0 of the temple-cutter cooperates with a fixed member or blade a the movable member being hooked (see Fig. 2) and operating as in the patent referred to, the filling end being brought against the fixed blade by the movement of the yoke hereinbefore referred to, after which the movable cut- -ter 0 on the temple is operated at the next forward beat of the lay, the hooked end of such movable cutter drawing the filling against the blade a and severing it. I have in Figs. 2 and 3 indicated the temple as a whole by T. After the thread has been thus cut adjacent the selvage of the cloth a short piece remains retained by the holding device, and it will be so retained until the actuatingarm p is again moved from full to dotted line position, viewing Fig. 5, to separate the holding-jaws k if, whereupon the thread will be released. The flexible or non metallic facing of one of the jaws of the holding device enables the filling end to be held, yet without running the risk of severing it by pinching when the jaws are closed.

The filling-thread is not rigidly held by the jaws of the holding device, but is permitted to draw through as the said device returns to normal inoperative position, since the distance to the edge of the cloth at such time is greater than when the holding device is in position to hold the thread-viz. directly over the lay.

The branches h 13 are considerably separated, as shown, so as to permit the thread to parted, but not to be entirely released.

Should the shuttle be improperly boxed when the yoke Y is moved toward the lay, the end of the branch p will engage the shuttle and, operating precisely as does the shuttlefeeler 'y in United States Patent No. 628,228, will prevent the movement of the dog m into position to be engaged by the hunter G and the transfer of filling will be prevented. The movement of the yoke into operative position is governed bya suitable set-screw 90, mounted in an ear A of the bracket A the setscrew being held in adjusted position by a suitable lock-nut 95, said set-screw acting as a stop for the yoke when it reaches its operati ve position, as shown in Fig. 6.

My invention is not restricted to the precise construction and arrangement herein shown and described, as various modifications may be made or a rearrangement of parts elfeoted without departing from the spirit and scope of my invention.
